I don't know how I stumbled upon these but apparently, a day ago... JOYSOUND (a karaoke system in Japan) posted the first line of each full song from Party Queen on their site. Some of the lyrics look very interesting. I also wonder if you can go into a JOYSOUND karaoke place or even use the Wii version in order to listen to them?
This seems to confirm that the three interludes are taskebab, a cup of tea, and Serenade in A minor.
Party queen - Party queen!… Saturday night
NaNaNa - tick… tick tock tick… don't
Shake It♥ - O-Lailaila… O-Lai I ・ girls
(expected.)
call - 君は覚えてなんかいないんだろう
Letter - そっちはどうだい?まだ今でも
Reminds me - 疲れた身体と一緒に 暗い部屋に
Return Road - 私のこの瞳に映ったあなたと
Tell me why - 今なにを想っているの? 本当は
the next LOVE - Lalala..... ママの鏡の前には(
She mentions 'mama' here and being in front of a mirror with her.)
Eyes, Smoke, Magic - パパは今日もポップコーン片手に
(Jeez, she says POPCORN in it! It looks like it says "Today, papa has popcorn in one hand")
how beautiful you are - 今日も一日ありがとう その笑顔
The songs very much appear to get very dark after taskebab but picks up after a cup of tea.
